"We commonly hear that only a tiny percentage of Americans don't believe in God and that, as a Newsweek poll claimed this spring, 91 percent do. In fact, this is not true. How many unbelievers are there? The question is difficult to assess accurately because of the challenges of constructing survey questions that do not tap into the prevailing biases about religion."

"According to the American Religious Identification Survey, which interviewed more than 50,000 people, more than 29 million adults--one in seven Americans--declare themselves to be without religion. The more recent Baylor Religion Survey ("American Piety in the 21st Century") of more than 1,700 people, which bills itself as "the most extensive and sensitive study of religion ever conducted," calls for adjusting this number downward to exclude those who believe in a God but do not belong to a religion."

"Contrast this with a more recent and more nuanced Financial Times/Harris poll of Europeans and Americans that allowed respondents to declare agnosticism as well as atheism: 18 percent of the more than 2,000 American respondents chose one or the other, while 73 percent affirmed belief in God or a supreme being."

"A more general issue affects American surveys on religious beliefs, namely, the "social desirability effect," in which respondents are reluctant to give an unpopular answer in a society in which being religious is the norm. What happens when questions are framed to overcome this distortion? The FT/H poll tried to counteract it by allowing space not only for the customary "Not sure" but also for "Would prefer not to say"--and 6 percent of Americans chose this as their answer to the question of whether they believed in God or a supreme being. Add to this those who declared themselves as atheists or agnostics and, lo and behold, the possible sum of unbelievers is nearly one in four Americans."

"All this helps explain the popularity of the New Atheists--Americans as a whole may not be getting too much religion, but a significant constituency must be getting fed up with being routinely marginalized, ignored and insulted. After all, unbelievers are concentrated at the higher end of the educational scale--a recent Harris American poll shows that 31 percent of those with postgraduate education do not avow belief in God (compared with only 14 percent of those with a high school education or less). The percentage rises among professors and then again among professors at research universities, reaching 93 percent among members of the National Academy of Sciences. Unbelievers are to be found concentrated among those whose professional lives emphasize science or rationality and who also have developed a relatively high level of confidence in their own intellectual faculties. And they are frequently teachers or opinion-makers."
